In this case the con- 10o ductors C, insulated asbefore, are separated by large wires E E, laid in between them, whichhold them apart so that they can be completely surrounded by water I) assoon as submersion takes place. These wires mayall be straight, or maybe arranged spirallyabout the insulated conductors. Other large Wiresmay be arranged between the insulated conductors and the armor A, and iffound con! venient the Whole may be eabled together. It will be seenthat the water D lls up all the intermediate spaces, flowing in betweenthe interstices ot' the armor A. Another method is to arrangeaseries ot'pierced disks, F, Figz, at short distaueesapart, and run the insulatedconductors through them. This, whileholding` the conductors together,serves also to maintain them at the proper distance from one another.

I may in any ot the hereinbefore-deseribed methods of construction,after bunching the severalconducting-wireslooselytogetl1er,leave themwithout other protection, or armor them with galvanized wire or othersuitable material, or draw them into pipes. If I employ pipes, they mustbe perforated, so that the water may be freely admitted.

I claim as ot' my inventionl. Au electric cable comprising; an` outercovering or armor having' openings through which Water eau Free-ly pass,aud a series oi' insulated conductors separated and held apartthroughout their entire length by means such as described, which willpermit a free circulation ofthe Water around and between the severalconductors, substantially as set l'orth.

2. In an electric cable, a series ot' independ ent conductors insulatedwith Water-proof material, said conductors beine: separated and heldapart by means of a filling;` ot' spongy or fibrous material or thespecilied equivalent therefor, substantially as described.

In testimony whereof' I have signed my name to this specitieatiomin thepresence ol" two subscribing witnesses, this 20th day ot Septem ber,1881.
